Musical instruments — what they are made of
4 musical instruments objects, broken down.
| Object | Made of |
|---|---|
| Guitar string | A high-carbon steel core with a wrap of nickel or bronze — or, on a classical guitar, nylon. |
| Piano key | A spruce or basswood lever with an acrylic top and a plastic sharp — ivory has been out of use for decades. |
| Violin bow | A pernambuco or carbon fibre stick strung with horsehair, which grips the string only because of rosin. |
| Drum head | A polyester film tucked into an aluminium hoop with epoxy — plastic replaced calfskin in the 1950s. |
